Investigation of the Effect of Wind Power Plant Control Modes on the Phenomenon of Fault-Induced Delayed Voltage Recovery(FIDVR)

In areas where the motor load is the predominant load, when the short circuit occurs, the speed of the motors decreases and their power reactive consumption increases, which causes some delays in voltage recovery after fault clearance. This delay can cause operation of protection systems and load shedding. Fault-Induced Delayed Voltage Recovery is a phenomenon in which the voltage level does not reach the pre-fault value immediately after the fault is cleared. If the Voltage recovery delay is significant, the wind power plant will be disconnected from the power system, which causes other problems in the power system. The purpose of this paper is to evaluate the effect of different wind power plant controls on voltage recovery delay. Wind power plant modeling is based on IEC61400-27-1 standard. Also in this paper the effect of location of wind power plant and the ability to Low Voltage Rid Through of wind power plant is considered. All the simulations are performed in DIgSILENT PowerFactory 2021 software.
